If two liquids A and B from minimum boiling azeotrope at some specific composition then

Answer»

A-B ineractions are stronger than those between A-A of B-B interactions.
Vapour pressure of solution increases because more mumber of molecules of liquids A and B can escape from the solution.
vapour pressure of solution decreses because less NUMBER of molecules of only one of the liquids escape from the solution.
A-B interactions are WEAKER than those between A-A or B-B.

Solution :if two liquids on mixing are to form a MINIMUM boiling AZEOTROPE, the vapour pressure of the solution formed MUST be maimum (boiling point will be minimum). This can happen if A -B interactions are weaker than both A-A and B-Binteractions.
